The Shaman is an interesting class. Specializing in buffs via totems, both to themselves and their allies, they are a great asset to any group and are formidable opponents by themselves. The Shaman has three primary choices when it comes to talents: Spell DPS, Melee DPS, and Healing, and they are more than competent at any of these three jobs, whichever is chosen. buy wow gold here.

Elemental - 41/0/20
Elemental is the Shaman Spell DPS tree. With the proper shaman gear, the shaman can dish out some serious damage with your Lightning and Shock spells. This shaman tree is also fairly simple as far as choosing what to get: The entire second tier of talents is relatively subpar; Improved Fire Nova's effect is too minimal; Elemental Devastation attempts a hybrid spellcaster/melee tactic that gear simply makes unrealistic; Unrelenting Storm is a decent talent, but is surrounded by better; Elemental Shields is detrimental to Eye of the Storm's effect. The points left over find happy homes in Restoration to aid your survivability, and in the case of Tidal Mastery even adds to your DPS. It may be worth considering exchanging Totem of Wrath for Nature's Swiftness, depending on which you feel you could use more. buy wow gold here.

Enhancement - 0/46/15
Enhancement focuses on Shaman Melee DPS. Better for sustained DPS and without the mana problems of Elemental, Enhancement is usually the choice for PvE, whereas Elemental is more effective in PvP. Still, geared and played well, both are viable for either situation. Enhancement is much the same as Elemental in the sense that the talents not worth taking are, for the most part, fairly obvious, either by their own merit (or lack thereof) or the presence of stronger talents around them. As with Elemental, the rest of the points are put into Restoration to aid in healing, if only yourself. Overall another strong talent tree, and choosing this or Elemental comes down largely to preference.

Restoration - 0/5/56
No one would be surprised to hear that Resto, as a healing tree, is the preferred tree for groups and raids, which usually require healers more than anything else. What may surprise you, however, is the PvP viability of Resto: while the shaman won't be doing much damage, you'll have a ton of survivability and can wear your opponent down. In this build, I focused primarily on PvE healing. While Improved Reincarnation's usage is limited and you may not want to take that talent regardless, if you plan to PvP as a Resto shaman, it may do you good to take three points out of Healing Grace and two from Tidal Focus to pick up Focused Mind and max out Nature's Guardian. buy wow gold here.

Enhancement/Resto Hybrid - 0/35/26
If you find yourself being expected to heal often enough to invest some points in the Resto tree but not enough to go full Resto, and are willing to live with slightly reduced DPS effectiveness, this build may strike a balance that works for you. Going down far enough in Resto to pick up Nature's Swiftness gives you a solid foundation for healing when you need to. It isn't quite enough for main healing difficult things, such as raids or Heroic instances, but if you have enough gear it should be enough. The loss of Shamanistic Rage and Unleashed Rage damages your effectiveness DPSing in a group, but if you need the healing talents, you probably weren't DPSing much in a group anyway. Worth a try if respec costs are getting to you. buy wow gold here.
